Other Modifications
Old Black has also been customized with a small toggle switch in the front of the guitar, between original pickup volume and tone adjustment knobs. This switch is not a coil tap, as would commonly be assumed, but rather is a switch that allows Young to bypass the potentiometers and capacitors and send his sound directly to his amplifier (a late-1950s Fender Deluxe).
Additional modifications from the original factory condition include the addition of a Firebird pickup installed in the bridge position (not just a covered P-90 as once thought), a metal truss rod plate, and a screw-fender washer combination replacing the standard strap knobs. Old Black has rarely been seen without Neil Young's famous peace symbol and dove guitar strap, which has also seen modifications over the years—most notably, its attachment to a Levy's wide guitar strap.
